Abstract
The utility model relates to the technical field of a slip ring detacher on a motor, particular to a slip ring puller. The puller comprises an extractor, a guide rod arranged in the middle part of the extractor, a hydraulic jack and a hydraulic workstation, wherein one end of the extractor is threaded to an inner sleeve of the slip ring while the other end is connected to the hydraulic jack which is connected to the hydraulic workstation. The extractor and the inner sleeve of the slip ring are connected through a high-strength bolt so as to match with the hydraulic jack, adjust the working pressure of the hydraulic workstation, keep the pressure for a period of time, and smoothly take out the slip ring from a rotating shaft. The puller solves the problem of insufficient force and lowers the manufacturing or maintenance costs of the slip ring.
Description
Technical field
The utility model relates to a kind of utensil of dismantling slip ring on the motor, particularly a kind of slip ring extractor.
Background technology
The slip ring of synchronous generator in use should transmission current, bears mechanical force again, and majority all is to be enclosed within the rotating shaft of motor by the heating after heat, to guarantee the normal use of slip ring.In case when motor broke down, often slip ring was again intact, needs the disintegration motor, must dismantle earlier slip ring in good condition.Because the structure of slip ring is special, and the special material Zhao insulating material of one deck is arranged between slip ring and the wheel hub, its mechanical strength is low, can not bear bigger pulling force, otherwise destroys insulation easily.For the method for dismounting of slip ring, generally all consider to adopt belt to take off son and claw or utilize jack to eject, special for some structure, the slip ring that the locus is less, common tool and method can't solve this type of special dismounting, damage slip ring easily.
The slip ring of the major-minor engine 5GMG201E of HXN5 locomotive for example, be assembled in the outside of end cap, because its structure is special, conduction when its four slip rings are worked, interference fit is adopted in inner sleeve and rotating shaft, the parts of isolating with insulating material between four slip rings and the inner sleeve, during assembling and the magnitude of interference of rotating shaft reached 0.12mm, the strength of extracting approximately needs 60T, in case need the disintegration motor, at first will dismantle slip ring in good condition, but existing structure of taking off son and jack are owing to be subjected to the restriction in strength and space, also can't solve, cause the slip ring manufacturing or the cost of overhaul too high.
The utility model content
The purpose of this utility model is, a kind of slip ring extractor is provided, and guarantees the slip ring amount of not stressing restriction when dismounting, and is injury-free, and it is even to claw strength, can dismantle slip ring smoothly in good condition, has reduced the manufacturing or the cost of overhaul of slip ring.
The technical solution adopted in the utility model is: a kind of slip ring extractor, comprise extractor, be arranged at guide rod, hydraulic jack and the hydraulic workstation in extractor centre, extractor one end is connected with the slip ring inner sleeve by screw thread, its other end is connected with hydraulic jack, and hydraulic jack is connected with hydraulic workstation.
Further, described extractor one end is connected with the slip ring inner sleeve by bolt.
Further, the described extractor other end is connected with hydraulic jack by screw.
The beneficial effects of the utility model are: extractor adopts high-intensity bolt to be connected with the slip ring inner sleeve, utilize it to cooperate with hydraulic jack, the operating pressure of regulating hydraulic workstation is to certain limit, the pressurize certain hour, not only can in good condition slip ring be clawed from rotating shaft smoothly, solve the problem of strength deficiency simultaneously, thereby reduced the manufacturing or the cost of overhaul of slip ring.

Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.
As shown in Figure 1, a kind of slip ring extractor comprises extractor 4, is arranged at guide rod 3, hydraulic jack 5 and the hydraulic workstation in extractor 4 centres.
Shown in Fig. 2,3, the end that extractor 4 is connected with the slip ring inner sleeve, it circumferentially is provided with a plurality of screwed holes.
During use, guide rod is installed on the machine shaft, is positioned in the cavity of extractor 4, and extractor 4 one ends are connected with the slip ring inner sleeve by bolt 2, and its other end is connected with hydraulic jack 5 by screw, and hydraulic jack 5 is connected with hydraulic workstation.After installing, connecting, the operating pressure of regulating hydraulic workstation is to certain limit, and the pressurize certain hour just can be smoothly, in good condition slip ring is clawed from rotating shaft, drops on the guide rod 3.Not only solved the not enough problem of the strength of generally taking off son, also can not damage the insulation system of slip ring simultaneously, thereby reduce the manufacturing or the cost of overhaul of slip ring.
